MATRIX TYPE DISPLAY DEVICE AND ITS DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To prevent flicker from occurring without raising a frame frequency in displaying gradation by an FRC in a display device using switching elements each of which has a semiconductor layer. SOLUTION: In this display device, a gradation control part 191 shift- processes gradation registers which output multilevel data in a gradation register circuit 192 by horizontal and vertical synchronizing signals 193, 194. Then, it is possible to prevent flicker from occurring by dispensing ON/OFF patterns on a random basis in the same frame surface and between frames by this shifting process in this display device.
